Data for increase of Lymantria dispar male survival after topical application of single-stranded RING domain fragment of IAP-3 gene of its nuclear polyhedrosis virus

This data article is related to the research article entitled “The RING for gypsy moth control: topical application of fragment of its nuclear polyhedrosis virus anti-apoptosis gene as insecticide” [1]. This article reports on significantly higher survival of gypsy moth Lymantria dispar male individuals in response to topical application of single-stranded DNA, based on RING (really interesting new gene) domain fragment of LdMNPV (L. dispar multicapsid nuclear polyhedrosis virus) IAP-3 (inhibitor of apoptosis) gene and acted as DNA insecticide

Molecular alliance of Lymantria dispar multiple nucleopolyhedrovirus and a short unmodified antisense oligonucleotide of its anti-apoptotic IAP-3 gene: A novel approach for gypsy moth control

Baculovirus IAP (inhibitor-of-apoptosis) genes originated by capture of host genes. Unmodified short antisense DNA oligonucleotides (oligoDNAs) from baculovirus IAP genes can down-regulate specific gene expression profiles in both baculovirus-free and baculovirus-infected insects. In this study, gypsy moth (Lymantria dispar) larvae infected with multiple nucleopolyhedrovirus (LdMNPV), and LdMNPV-free larvae, were treated with oligoDNA antisense to the RING (really interesting new gene) domain of the LdMNPV IAP-3 gene. The results with respect to insect mortality, biomass accumulation, histological studies, RT-PCR, and analysis of DNA apoptotic fragmentation suggest that oligoRING induced increased apoptotic processes in both LdMNPV-free and LdMNPV-infected insect cells, but were more pronounced in the latter. These data open up possibilities for promising new routes of insect pest control using antisense phosphodiester DNA oligonucleotides

Biological control of gypsy moth (Lymantria dispar): an RNAi-based approach and a case for DNA insecticides

The discovery of the post-transcriptional gene silencing (PTGS) mechanism, widely known as RNAi (RNA interference),has contributed towards the elucidation of the cellular machinery involved in the response against viral infections based on gene silencing, and in developmental regulation of translational suppression. The application of RNAi in insect pest management (IPM),and gene functional analysis, has been of enormous importance. Unfortunately, as RNAi has many times proven to be difficult to examine in Lepidoptera, focus has shifted to other potential post-genomic options in IPM. Special attention has afforded to novel DNA insecticides based on preparations of short single-stranded fragments of baculovirus anti-apoptosis genes, which represent a safe and relatively rapid alternative approach for IPM. This paper focuses on the draw backs and advantages of DNA insecticides used in gypsy moth control and based on RNAi

Rethinking the intercultural communicative competence evaluation in higher education

The information and digitalization age, the current phase of globalization are changing the way we think about cultures and communities and, as language teachers and cultural trainers, potentially about what and how we teach. Intercultural communicative competence is as needed as ever in today’s world of geo-economic changes, migration, and rising ethnic and national tensions. To prepare future professionals, there have been different efforts in education including the intercultural and communicative components. The essential contradictions in the language and professional training of students, associated with insufficient attention to the issues of interaction of cultures in the content of university curricula, are highlighted. The Map of Intercultural Communicative Competence Formation in Higher Education is developed considering the contents of bachelor and master programmes for Russian and foreign students. The main emphasis is paid to the separate subjects in intercultural communication study. New approaches to the evaluation of the intercultural communicative competence of students in a multicultural environment are proposed, among which a special focus is placed on the need to organize international projects and conduct events in narrow professional fields. Some examples of tasks to assess the competence in cross-cultural communication show practical application and significance of those disciplines for university students in their future career

Foreign languages training features in digital environment of non-linguistic universities

The research is devoted to identifying the features of foreign languages training of non-linguistic universities students in the digital environment. The analysis of theory and practice on the research problem allows us to highlight a number of features that affect the formation of foreign language competence of non-linguistic universities students in the foreign languages training. It is worth including among them: updating the multicultural component of foreign languages training in a non-linguistic university; implementation of purposeful work on extracurricular preparation of students for the digital tools using; an electronic information and educational environment creation. The authors emphasize the importance of the multicultural component in foreign languages training, as it contributes to the development of the potential abilities of the students’ linguistic personality. Considering the second feature, the authors especially note that the use of digital tools provides great opportunities for the implementation of a method that most fully reflects the two main principles of the communicative approach to foreign languages training: motivation for learning and personal interest. Students are willingly involved in cognitive activities. The authors associate the third feature with the ability of students to work independently, since it is the independence that makes it possible to successfully adapt to work associated with rapidly changing technologies. This skill is especially important in correspondence or distance learning, when the student’s communication with the teacher is irregular. The presented features, according to the authors, make it possible to change the motivational attitude towards educational and future professional activities

The need for the application of modern chemical insecticides and environmental consequences of their use: a mini review

Currently, the use of insecticides is an acute problem. Due to rapid population growth, the primary task is to increase food production. Beyond abiotic factors (drought, soil salinity, etc.) that reduce crop yields, farmers face problems with insect pests that can decrease crop productivity up to 60%. Also, insects are carriers of severe viral and protozoan human diseases. The need for application of insecticides is not questioned but many of them cause resistance of insect pests to them. This, in turn, leads to the necessity to invent new insecticides that are safe and more effective for long-term use. Preparations based on conservative parts of nucleic acids, particularly contact DNA insecticides, could be used to solve insecticide resistance problem as control agents which are well-tailored to target insect pests. This mini review is devoted to these issues
